Marc Trestman has been fired as the Baltimore Ravens offensive co-ordinator and replaced
The team announced the decision on Monday, just a day after their 16-10 loss to the Washington Redskins, Baltimore's second successive defeat.
Marty Mornhinweg will take over as offensive co-ordinator for the remainder of the campaign.
The Ravens have struggled offensively, ranking in the bottom 10 for yards per game (338.2) and points per game (18.8). Trestman's career with the Ravens lasted 21 games.
"After very careful consideration, I have decided to make a change to our offensive coaching staff and have replaced Marc Trestman with Marty Mornhinweg as offensive coordinator for the rest of the season," coach John Harbaugh said in a statement.
"My obligations are to the team, the organisation and the fans to be the very best team we can be. We find ourselves one game out of the division and conference lead after experiencing two tough losses at home.
"We will work to be better in every aspect of our football team. Our expectations are high, and we look forward to fulfilling them.
"I appreciate and respect the efforts and contributions Marc has made to the team since his arrival. Marc is a good person and an excellent football coach."
